Image quality

When you want to pull detail out of tonal extremes, it helps if the image is 16-bit rather than 8-bit. The difference translates to over 4 trillion colours – extra data that helps to prevent banding and image break-up. Shoot in raw then open the image in Camera Raw; click the link below the image, go to the workflow options and set Depth to 16-Bits/Channel, then click Open.
